Guts & Glory: Walker - In the Shadows Security, #4

You can lie down and give up or you can rise and keep going... Walker's been living life by this motto since the age of twenty when the girl he planned his future with shattered his heart and left a hole in his soul. His time in the military, and current job at In the Shadows Security, have kept him moving, but he's always felt the ache of that loss. From the outside Ellie McMaster has led a seemingly perfect life, big house, rich adoring husband, fancy cars.
But it's all been a huge lie, one that started nineteen years ago when she walked away from her first love and the boy who stole her heart. Now time has run out for her and with nowhere to go and nothing left to lose she'll have to face down the pain of the past in hopes of saving her future. But Trace Walker isn't the carefree teenager she remembers, he's now a muscle-bound titan with nothing but hurt and anger shining in his blue eyes.
His time in the Army as a Night Stalker wasn't easy, and he didn't return home whole. Will he open himself up again and face the risks that come with having Ellie back in his life, back in his heart? Can this be their shot at a happily ever after, or their final goodbye? Note: Guts & Glory: Walker is the fourth book of the In the Shadows Security series, a six-book spin-off from my Dirty Angels MC series.
It's highly recommended to read both series in order. As with all my books, this has an HEA, no cliffhanger or cheating.
